Peg-shaped teeth are teeth that are smaller and narrower than what would typically occur. Peg-shaped teeth most commonly affect the upper laterals (second from the front) and can affect either one or both. Peg-shaped teeth are a form of microdontia caused by developmental disturbances due to congenital reasons. They often run in families, so if a parent or sibling has a peg-shaped tooth, x-rays may be recommended to check for peg-shaped teeth in early childhood. Peg-shaped teeth can be mild to severe, and several options are available to improve the aesthetic appearance. 


Dental bonding helps to improve the look of the peg-shaped teeth by adding composite resin, or a filling material, to change the colour, shape and size of the teeth. Bonding gives a great result and is the least expensive option, but it can chip and stain over time and needs to be repaired/replaced more frequently, so it is not considered the best long-term solution.  

Crowns/ Veneers

Crowns and veneers are considered a more long-term solution for peg-shaped teeth and offer the best coverage for the teeth. They can both change the shape, size and colour of the peg-shaped teeth as a more permanent solution. Both crowns and veneers are fabricated in a lab to fit precisely for the teeth. Crowns are caps that get bonded on top of the peg-shaped teeth, and veneers are thin coverings that bond to the peg-shaped teeth’ front surface. Crowns and veneers are around the same cost and significantly more expensive than bonding. Talk with your dentist about the right option for you based on your needs. 

Extraction/ Implant or Braces 

If the peg-shaped teeth are small and not saveable or if you are planning on getting braces, another option is to extract the peg-shaped teeth and either close the gap with braces or place an implant in the extraction site to replace the tooth.
